If desired the shoe 22 maybe locked in the adjusted position about such pivot by engagement of thestud 29 with other suitably disposed holes in the bar 21.

The other cramping shoe 23 is fitted to the slides 15 of the vise for.which purpose it is formed with sockets or hollow bosses 32 fittingthese slides. One or more set screws may be fitted to the hollow bosses32 in order more firmly to secure the shoe 23 to the slides 15.

Thus the cramping bar 21 may be disposed at right angles to the faces ofthe vise jaws l1 and 14 with the gripping surfaces of the cram-pingshoes '22 and 23 parallel to the vise jaw faces as shown in full linesin Figure 4;. If desired, however, the cramping bar 21 may be turned toan angle with the vise aw faces while the cramping shoe 22 may beadjusted both as to position along the bar 21 and also about the axis ofthe screw or pin 27 for dif ferent purposes, various positions of thecramping bar 21 and shoe 22 beingindicated by dotted lines in Figure 4.r a

For cramping a rectangular frame the shoes 22 and 23 may be formed toengage the interior and exterior angles of the frame. In themodification illustrated in'Figures 6 and 7 the movable shoe 23(provided with the socket 32 to fix the slide 15) is formed with a ledge33 to support the frame and with abutments 34 to engage its exterior ede. The abutments 34 are grouped along the ces'ired angle or maybereplaced by flanges extending from the ledge 33.

The relatively fixed shoe 22" is provided with abutments 35 toengage theinterior angle of the frame which is indicated in chain lines in Figure6 thus clamped between the two shoes, the abutments 35 being preferablysituated above a supporting surface 36 of the shoe 22 corresponding inheight to the ledge 33- and assisting that ledge in supporting the frameabove the cramping bar 21.

If desired similar ledges may be provided in the shoes illustrated inFigure 4 to support the work being'cramped.

What I claim is V 1. In a woodworkers vise the combination of a fixedjaw having a plate-like gripping face'and formed with a clamping base atright angles to its gripping face and with a circular recess in theclamping base having a restricted opening leading to the rear edgethereof, the fixed jaw being also formed with a bracket extending fromthe lower edge of its gripping face, a clamping screw carried by thebracket, a movable jaw operated by a screw engaging a nut carried by thefixed j-aw,two parallel cylindrical slides on the movable jawfittingguides in t-hefixed jaw and passing above the clamping base, a crampingbar provided with a head fitting the recess in the clamping base andwith a necklike portion narrower than and passing through the restrictedopening of the recess, a cramping shoe adjustably fitted to the bar anda cooperating cramping shoe formed with sockets fitting the ends of thevise slides, substantially as specified 2. In a woo'dworkers vise thecombination of a fixed jaw having a plate-like gripping face and formedwith a clamping base at right angles to its gripping face and with acircularrecess in the clamping base having a restricted opening leadingto the rear edge a bracket extending from the lower edge of its grippingface, a clamping screw carried by the bracket, a movable j aw operatedby a screw engaging a nut carried by the fixed aw, two parallelcylindrical slides on the movable jaw fitting guidesin thefixed jaw, andpassing above the clamping base, a cramping bar provided with a headfitting the recess in the clamping base and with a neck-like portionnarrower than and passing through the restricted opening of the recess,a cramping shoe adjustably fitted to the bar and provided withabutmentsto engage the interior edge ofa rectangular frame and acooperating cramping shoe formed with socketsfih ting the endsiof thevise slides, and formed with a ledge to support the frame and withabutinents to engage its exterioredge, substantially as specified.

3. In awoodworkers vise, the combination with a fixed jaw'hav ing guidesand a movable jaw, of a slide on said movable aw cooperatingwith saidguides, means for securing the fixed jaw to a bench with the movablejawslide passing through the fixed jaw above the bench surface, a crampingbarextending from the rear of the fixed jaw and adjustable to differentangular positions with respect thereto, a cramping shoe adjustablyfitted to the bar and a co-operating cramping shoe fitted to the slideof the movable jaw, substantially as specified. V
